Is it okay to use the generic memory but not so fancy looking green RAM for gaming?

Transcend JetRam DDR4-2666 Game Performance Test

Memory module with black colored PCB are often marketed as gaming memory even though youll still be able to find those generic memory with non-black colored PCB that shares the same or similar specifications. Although these generic memory usually doesnt comes with any XMP profile like these gaming memory does, there are chances youll still be able to give it a little push for a slightly better performance if youre using a motherboard that supports memory overclocking.



To put this to the test, well be doing a quick and simple game performance test using the generic looking Transcend JetDram DDR4-2666 (JM2666HLB-8G) compare it against a gaming memory that has a 3200MHz CL16 XMP profile.



Although Samsung, SK Hynix and Micron are the commonly used memory IC nowadays, the Transcend JetRam DDR4-2666 are using the memory IC from SpecTek which can be found on quite a number of generic memory in the market. Just so you know, SpecTek is a wholly owned division of Micron Technology that develops cost effective memory solution.

As for which memory IC from SpecTek are used on the Transcend JetRam DDR4-2666, we cant really determine it using the Thaiphoon Burner as usual because these information has been removed for some reason.

Test System Setup

CPU Intel Core i7 8700K @5.0GHz
Motherboard ASUS ROG Maximus X Apex
Memory Transcend JetRam 8GB @3200MHz CL19
Graphics Card NVIDIA GeForce RTX 2060 Founders Edition
Power Supply Enermax MaxTytan 1250W
Primary Storage ADATA SU800 256GB
Secondary Storage WD Black 6TB
CPU Cooler Raijintek Orcus 240
Chassis Cooler Master Test Bench V1
Operating System Windows 10 64bit

In this test, well be using the popular battle royale title PLAYERUNKNOWNS BATTLEGROUNDS to gauge the performance difference between the Transcend JetRam DDR4-2666 (stock and overclocked) and gaming memory running at 3200MHz with XMP.



As its name suggests, the Transcend JetRam DDR4-2666 runs at 2666MHz CL19. Despite its generic look, the specifications here are actually very similar to quite a number of gaming memory in the same category.



For our gaming memory, weve enabled the XMP profile so that it runs at its factory optimized speed and timings. Weve confirmed that its actually using Samsung B-die memory IC, but the one we have here is a 3200MHz CL16 kit. Its not exactly the highly sought after 3200MHz CL14 that enthusiasts are looking for.

JetRam 2666MHz CL19 Gaming 3200MHz CL16

Since the JetRam doesnt have a XMP profile to begin with, were running it at its stock speed 2666MHz. We run the few set of test each for the memory separately and heres the result:

FPS Min Max Average
JetRam 2666MHz CL19 20 115 82
Gaming 3200MHz CL16 40 121 86

While the difference in average fps doesnt seems to be very significant, the effect of having a higher CAS latency can be seen in the minimum fps recorded.



The data are then populated in a frame time graphic so that we can get a better idea on how the game behaves under different memory frequency and CAS latency. At a seemingly more than playable average 82 fps, the stutters caused by random fps drop and spike for certain scenes can be a problem if youre playing competitively.

JetRam 2666MHz CL19 JetRam 3200MHz CL19

We settled down with 3200MHz CL19 for the Transcend JetRam DDR4-2666 without any adjustment to the timings and relevant voltage, but thats pretty much we can do for now.



Tightening the timing doesnt seems to be a good idea because we ended up with an unstable system for going lower than CL18. Were able to run the game with CL18-18-18-39 2T but it yields very minimal difference in performance and random BSOD still happens once in a while.

FPS Min Max Average
JetRam 2666MHz CL19 20 115 82
JetRam 3200MHz CL19 36 120 84

Although the raise in average fps after the overclock seems to be very minimal, the minimum fps recorded almost doubled and that really improved the game play in overall. The game play are noticeably smoother even though random stutters still occurs in more complex scenes.



By comparing the before and after result, were actually getting a more consistent frame rate after the overclock. As were actually getting a good gain in speed without sacrificing the latency, the fps drops and spikes doesnt goes as crazy on the 3200MHz CL19 as compared to 2666MHz CL19.

JetRam 3200MHz CL19 Gaming 3200MHz CL16

We then compare the result for both memory running on 3200MHz to see what kind of performance gain are we getting despite the difference in the CAS latency.

FPS Min Max Average
JetRam 3200MHz CL19 36 120 84
Gaming 3200MHz CL16 40 121 86

By having the same latency but higher speed, were able to achieve a pretty decent result with the Transcend JetRam DDR4-2666. The better representation of reduced performance gap can be seen in the minimum fps, which is now 36 instead of 20. Thats a 80% increase as compared to the 2% increase in average fps.



In the frame time graph above, we can see a much more consistent frame rate for the Transcend JetRam DDR4-2666. Its not exactly performing on par with the gaming memory running at 3200MHz CL16 of course. At least we can see that its much better than what were getting from 2666MHz CL19. To put it simple, a much more playable game in overall.

Final Thoughts

Heres something to clarify before we wrap things up were not trying to prove that any brand is more superior than the other. Its more of showing what you kind of performance you can draw from a generic memory that is not marketed as a gaming memory.



These generic memory might not be using any of the memory IC that you will normally find on a gaming memory that has a pretty good headroom for overclock, but you still can give it a slight push if youre using a motherboard that allows you to overclock your memory.

For the Transcend JetRam DDR4-2666 we have here, its more of a memory kit for those who wants reliability for work instead of the performance for gaming. Because of this, theyre usually comes at a cheaper price Transcend JetRam DDR4-2666 are priced at RM 249, thats like almost RM 50 cheaper than some of the value gaming memory youll find in the market. If you dont mind the generic look, these generic memory will still get the job done just like your value gaming memory, but at a lower cost.
